The Waste to Biogas Mapping Tool is an interactive map created to connect organic waste producers (e.g. grease rendering facilities or food processing facilities) and potential users (e.g. wastewater treatment facilities) for the purpose of biogas production through co-digestion. Co-digestion is the addition of high strength wastes such as food scraps and fats, oils, and grease (FOG) to a wastewater treatment plant or dairy digester. Co-digesting organic waste materials allows facilities to save and make money while reducing greenhouse gas emissions, providing a renewable energy source, and diverting valuable resources from landfills and/or sewer pipes.
